Another Duron/TBird temperature question

My TBird runs idle between 35° - 39° Celsius. After heavy duty, it reaches 52° - 56° C.

Some people I know and many of you in this forum, acording to your postings, don´t get such high temperatures, although they have the same CPU/Mainboard/Cooler configuration. I know, 56°C is nothing to worry about, but I´m confused why most of the other Durons/Tbirds with the same configuration run 10° or more below my numbers. I´m sure I´ve mounted the HS/fan correctly, and I´ve also put some thermal compound between the CPU/HS.

I´ve heard the thermal sensor on the ABIT KT7 might show lower numbers, if it was put too far away from the CPU during mounting.
Or does each Athlon reach different temperatures anyway?

Anyone an idea??

 
The temperature readings for Socket A boards is pretty much a scam. This is for the following reasons:

1. The thermistor is outside of the CPU, so individual placement would affect individual readings.

2. Thermistors are alrady known to sometimes be inaccurate.

3. Sometimes the BIOS would add on to the reading to get a more accurate reading.

4. Sometimes the software monitor would do the same thing.

But yeah, it does feel better if your CPU runs "cool". My temps jumped 5C when I changed the BIOS. Don't care, because it still runs the same.
 
although not completely accurate, it does give you a good baseline for temp. Check it at oem speed, then try to keep it in the same neighborhood when overclocking. the number may be a little off, but it does give you a reference point. It should stay at about the same amount of inaccuracy at least.
 
I disagree with it giving a good baseline temp. It still prevents any kind of comparison between socket a cpu temp comparison. And updating the bios screws up the baseline.

The problem wiht many people saying that their kt7/a7v equipped duron/t-birds are running at 35C or lower is due to the fact that they are using early bios'. For example, there is a user right now claiming his duron 1ghz 1.8v is running at 34C. Sure, that would be possible if his case temp is 10C. But Somehow, i doubt his case temp is 42F.

Later kt7/a7v bios, as forementioned, add some compensation to help correct these problems. However, many people don't believe this, and rather choose to believe that the new bios is a)screwy and b)makes their cpu run warmer.

At best cases, a duron/t-bird at stock speed/voltage would run roughly 12-15C over ambient. One overclocked over 900mhz with increased voltage is likely to run 18C or higher over ambient.

Renob,

Which bios did you have before?


Also, there are problems with the MSI boards(which have no compensation) and the large number of users using old kt7 Bios(hence those people are reporting cpu load temps of 5C over ambient).

Ummm... He is measuring Heatsink temp, not CPU temp. And definately not cpu core temp. It is an improperly done test, and it isn't a "real" temp probe. And it is also known that the problem is an APCI issue, nothing major.

And you can tell that he claims his a7V onboard sensors(which most people use) is running 7C too high. NO, not too high, its a built in-compensation.
On Top of That, Idle temp doesn't mean Anything when Overclocking. The Full Load Heatsink temps remain the same, and that is the important number when overclocking
